The S of this species differs from E. semiglobosa Westr., as 

 also from E. picina (Blackw.) or Lophocarenum erythropus Menge, 

 by the elevated part of the head being longer, about double as long 

 as it is high, flattened, not high and arched. The anterior central 

 eyes are posited in the midst of the face, i. e. as far from the top 

 of the head as from the egde of the clypeus — not, as in E. semiglo- 

 bosa, visibly higher than the middle of the face; the forehead (the 

 area above the anterior central eyes) is covered with hair, which 

 gives it a rugous appearance, whereas in E. semiglobosa the fore- 

 head is smooth and shining. The extremity of the tibial joint of the 

 palpus of $ is above drawn out into a long, lamellar, somewhat 

 tapering projection , which is strongly and almost at right angles cur- 

 ved outwards: its slender apex is somewhat notched; at its exterior 

 side, near the middle, is seen a strong process directed outwards 

 and almost parallel with the extremity of the lamellar projection. 



A specimen of Waleken. borealis kindly sent me by Cambridge, 

 differs from Swedish specimens of E. erythropus by its head being 

 slightly higher in front, and its upper surface thus a little sloping, 

 not quite as horizontal as in the Swedish specimens; but I cannot 

 discover any other difference, and do not consider this to be of 

 specifical significance. — As regards Lophocarenum erythropus Menge,

Of this species I have a 3 ad. determined by Westring himself: 

 it agrees fully with Micryph. ochropus Ohl. and Walck. minima 



1) V L. aciculatum" in the explication of this plate is evidently a misprint 

 or lapsus calami for "L. apiculatum".
